19 Jun 2025 — urllib3 is a user-friendly HTTP client library for Python. Prior to 2.5.0, urllib3 does not control redirects in browsers and Node.js. urllib3 supports being used in a Pyodide runtime utilizing the JavaScript Fetch API or falling back on XMLHttpRequest. This means Python libraries can be used to make HTTP requests from a browser or Node.js. Additionally, urllib3 provides a mechanism to control redirects, but the retries and redirect parameters are ignored with Pyodide; the runtime itself determines redirect... • https://github.com/urllib3/urllib3/commit/7eb4a2aafe49a279c29b6d1f0ed0f42e9736194f • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •
CVSS: 5.3EPSS: 0%CPEs: 1EXPL: 0CVE-2025-50181 – urllib3 redirects are not disabled when retries are disabled on PoolManager instantiation
https://notcve.org/view.php?id=CVE-2025-50181
19 Jun 2025 — urllib3 is a user-friendly HTTP client library for Python. Prior to 2.5.0, it is possible to disable redirects for all requests by instantiating a PoolManager and specifying retries in a way that disable redirects. By default, requests and botocore users are not affected. An application attempting to mitigate SSRF or open redirect vulnerabilities by disabling redirects at the PoolManager level will remain vulnerable. This issue has been patched in version 2.5.0. • https://github.com/urllib3/urllib3/commit/f05b1329126d5be6de501f9d1e3e36738bc08857 • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •
CVSS: 4.6EPSS: 0%CPEs: 2EXPL: 0CVE-2024-37891 – Proxy-Authorization request header isn't stripped during cross-origin redirects in urllib3
https://notcve.org/view.php?id=CVE-2024-37891
17 Jun 2024 — urllib3 is a user-friendly HTTP client library for Python. When using urllib3's proxy support with `ProxyManager`, the `Proxy-Authorization` header is only sent to the configured proxy, as expected. However, when sending HTTP requests *without* using urllib3's proxy support, it's possible to accidentally configure the `Proxy-Authorization` header even though it won't have any effect as the request is not using a forwarding proxy or a tunneling proxy. In those cases, urllib3 doesn't treat the `Proxy-Authoriz... • https://github.com/urllib3/urllib3/commit/accff72ecc2f6cf5a76d9570198a93ac7c90270e • CWE-669: Incorrect Resource Transfer Between Spheres •
